jiimi hendrix has his own chord, i rightly proclaim this as the Dempsey68 chord!

Oh yeah, forgot to mention, you didn't come up with it

That's the thing about music, basically every (useful/practical) chord you could ever come up with has been used before in some form or another.

Even with the "Hendrix chord," it had been used in jazz well before Jimi wrote Purple Haze. Not to say he stole it, because I'm sure he didn't, but even though he came up with it, he wasn't the first.

Edit: Braddigan plays Whirlwind a bit differently in that show. I'll try to find the studio recording or something for you, although it's not really that important. Here you go. There's a clip of the song about 40-50 seconds in.

Only play what you hear. If you don’t hear anything, don’t play anything.-Chick Corea
